FILM-MOUNT.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed May 20,1915. Serial No. 29,287.

To all whom it may concern:

3e it known that I, BENJAMIN L. SPITZER, a citizen of the United States,residing at the city of New York, in the borough of Manhattan and Stateof New York, have invented certain new and useful Improvements inFilm-Mounts, of which the following is a full, clear, and exactdescription.

This invention relates to film mounts and more particularly to mountsadapted for use with developed films, e., transparent positives ornegatives, being particularly adapted for use with radiographs or X-rayphotographs which are made by dentists to determine the location of thecavities in the teeth, before any work is commenced. Small films aremost frequently used for this purpose. being usually of dimensions notgreater than 3"x2-}", and it is the object of my invention to provide amount of a simple and cheap construction, which will permit such filmsto be viewed in transmitted light.

Other objects of the invention are to provide a mount similar to anindex card, which may be conveniently filed for future refer ence aftersuch data as is desired is written on the card; to provide a mount whichwill protect the emulsion side of the film from and to provide a mountwhich will cut off the transmitted and reflected light surrounding thefilm to cause the detail of the image on the film to stand out clearlyand distinctly.

\Vith these and other objects in view the invention consists of a cardhaving an opening therein covered by a backing of light transmittingmaterial such as celluloid. which forms with the card a pocket adaptedto receive the film and to expose it before the opening in the card sothat it may be properly viewed in transmitted lignt.

In the accompanying drawings, Figure l is a view showing the front faceof the mount and film; and Fig. 2 is a view of the rear face of themount.

The card 1 upon which the film is mounted is of any opaque-material suchas heavy paper and the like, upon which may be written the name andaddress of the patient whose teeth are shown in the accompanyingphotograph, the dentists diagnosis, an

such other data as may be desired. The card is preferably of a size tobe conveniently filed in any of the standard filing cabinets. Cut in thecard, preferably adja cent its center, is a rectangularly-shaped orother suitably shaped opening 2 corresponding in shape but slightlysmaller in size than the radiographic film 3, which is positioned behindthe same and which therefore rests against the face of the card surrouning the opening.

Secured to the back of the card and cov ering the opening 2, is a pieceor strip 4: of light-transmitting material, such as celluloid, whichserves as a backing for the film to hold it in place. In theconstruction shown, the backing 4 is somewhat larger in size than theopening 2, but

preferably of the same shape, or in other.

words, is about the size of the film. The

hacking provided with projections or tabs 5 which lit into slits cut inthe card, one of the slits being preferably arranged adjacent to andparallel to each side of the rectangularly shaped opening. To insert thefilm in place, three tabs or projections a re first passed through theircorresponding slits thereby forming a pocket in which the film isplaced, which will correctly position it before the opening 2 in thecard. The remaining tab is then inserted through its slit and the filmis then held on all four sides so that it cannot be displaced. The filmis placed with its emulsion side against the barking which serves as aprotector for the same and prevents it from being scratched or otherwiseinjured through careless handling.

While the backing 4 may be of any lighttransmitting material yet it ispreferred to use a translucent backing which will elimiuatc any foreignobjects from the transmitted light such as the filament of an electriclamp, which would impair the clearucss of the detail of the picture. Thesurface of the opaque card is preferably colore-cl black and cuts otfthe transmitted and reflected light which'causes the image to stand outmore clearly when viewed in transmitted light.

While I have shown one form of means for securing the light'transmittingbacking in place. yet it is apparent; that this backing may be securedin place in other ways, and yet form. with the face of the cardsurrounding the opening, a pocket which is adapted to receive the filmand hold it in place, and it is intended that all suehconstructioqslshall come within the purview of the invention as setforth in the appended claims.

I claim:

1. A mount for radiographic' films and the like, comprising an opaqueindex-card having an opening therein, said card having a plurality ofslits therein surrounding the opening, and a backing oflight-transnitting material having projections thereon adapted to enter said slitsand forming with the face of the card surrounding said opening, a pocketto receive the film.

2. A mount for radiographic films and mitting material covering saidopening and 20 secured to the edge of said card around said opening,said backing forming withthe faceof the card surrounding said opening apocket of a proper size to receive the film.

In witness whereof, I subscribe my sig- 25 nature, in the presence oftwo witnesses.
